Tasks 3 and 4 were not marked as completed despite following all lab instructions and successfully executing the SQL queries. I independently verified the tables using BigQuery CLI: correct schemas, 462 unique SKUs, 463 combined rows, and zero data mismatches against the source. All required operations completed successfully, but the grader continued to reject both tasks. Please review the automated grading logic for Tasks 3 and 4.
